CROSS REFERENCE TO RELATED APPLICATIONS

This application is a divisional application of U.S. patent applicationSer. No. 11/287,796, filed Nov. 28, 2005, published as 2007-0123443, nowallowed. The entire disclosure of which is incorporated herein byreference in its entirety.

BACKGROUND OF THE INVENTION

The present invention relates to a composition for protecting a surface.In particular, the present invention relates to a composition forforming a water resistant and high gloss coat on a surface.

Soiled vehicle surfaces have been cleaned for many years using a varietyof compositions and methods. Such compositions can be as simple as soapsolutions or organic dish soaps or common all-purpose utility cleaners.In commercial or industrial vehicle cleaning operations, such assemi-automatic and completely automatic vehicle washes, a variety ofcleaning systems have been used that often contain a pre-rinse orpre-cleaning step followed by a cleaning step using a low pH and/or highpH detergents and a combination of one or more steps using waxes,rinses, anti-rust agents, mechanical dryers, etc. Such vehicle cleaningoperations can be embodied in a retail cleaning operation designed forcleaning vehicles by personal owners or by vehicle wash personnel.

When running a vehicle through a commercial vehicle cleaning wash, it isdesirable to apply a wax after the vehicle has been washed in order tocoat the vehicle with a protective film. The protective film is waterresistant. The wax is typically applied to the vehicle by spraying theaqueous solution onto the vehicle at the end of the wash operation,rinsing the vehicle with water, and air blowing the excess water fromthe vehicle. The result is a hydrophobic surface that is formed on thesurface of the vehicle.

A class of waxing composition commonly available includes a formulationcomprising surfactants, solvents, and a wax to form a shiny hydrophobicsurface. Silicones are very hydrophobic materials with a high refractiveindex that, when used in vehicle waxing compositions with othercomponents such as nonionic detergents, will form a shiny surface overthe vehicle. After a wash, the surface of the vehicle is left with aresidual negative charge. This residual charge creates an electrostaticattraction to molecules with a tendency to accept electrons. Therefore,molecules containing quaternary amines will be attracted to the surface.If reactive protonated amino siloxanes are used in the formulation, theywill be electrostatically attracted to the surface and will eventuallypolymerize, creating a hydrophobic film that rejects water and helps toretain gloss enhancing agents.

BRIEF SUMMARY OF THE INVENTION

A composition of the present invention includes an alkoxyaminofunctional dialkylpolysiloxane, a long chain silicone quaternaryblend, a silicone fatty amino quaternary polydimethylsiloxane, acarboxylic acid, a surfactant, a cosurfactant, and water.

In one embodiment, the composition of the present invention constitutesabout 0.002% to about 20% by weight alkoxy aminofunctionaldialkylpolysiloxane, about 0.002% to about 50% by weight long chainsilicone quaternary blend, about 0.002% to about 20% by weight siliconefatty amino quaternary polydimethylsiloxane, about 0.01% to about 5% byweight carboxylic acid, about 0.001% to about 20% by weight surfactant,about 0.001% to about 20% by weight cosurfactant, and water.

A method of coating and protecting a vehicle surface includes rinsingthe surface, washing the surface with a cleaning solution, applying aprotective coating onto the surface, spraying the surface with water,and air-drying the vehicle. The protective coating includes an alkoxyaminofunctional dialkylpolysiloxane, a long chain silicone quaternaryblend, a silicone fatty amino quaternary polydimethylsiloxane, acarboxylic acid, a surfactant, a cosurfactant, and water.

DETAILED DESCRIPTION

The composition of the present invention may be employed in any of awide variety of situations wherein a hydrophobic film-forming coat isdesired. The composition is especially useful in applications where itis desired to have the resulting film protect a surface from water andnormal wear. In addition, by incorporating a long chain siliconequaternary blend into the composition, the resulting film provides ashiny and aesthetically pleasing surface. Such applications include, butare not limited to: vehicle care, easy to apply long-lasting high glosspolishes, and water rejection and protection of hard surfaces.

The present invention is a stable concentrated aqueous solution thatleaves a polymeric film of an alkoxy aminofunctional dialkylpolysiloxanemix with a quaternary long chain silicone blend on a surface afterrinsing with water. The resulting film creates a protective hydrophobic,high gloss barrier resistant to common vehicle wash chemicals. Thecomposition can be applied at the end of the vehicle wash operation byspraying onto the surface of the vehicle, rinsing out with water, andair blowing dry. Unlike most film-forming compositions currently knownin the art, the vehicle surface does not have to be dry for the film tobe effective. Although the composition is discussed as being applied tothe surface of a vehicle, the composition may be used on any surfacewhere a hydrophobic, high gloss protective film is desired.

The composition of the present invention includes an alkoxyaminofunctional dialkylpolysiloxane, a long chain silicone quaternaryblend, a silicone fatty amino quaternary blend, a surfactant, acosurfactant, and water. All concentrations herein are expressed inweight percent, unless otherwise stated. Suitable componentconcentrations in the composition of the present invention range fromabout 0.002% to about 20% alkoxy aminofunctional dialkylpolysiloxane,about 0.002% to about 50% long chain silicone quaternary blend, about0.002% to about 20% by weight silicone fatty amino quaternarypolydimethylsiloxane, about 0.01% to about 5% by weight carboxylic acid,about 0.001% to about 20% surfactant, and about 0.001% to about 20% byweight cosurfactant. Particularly suitable component concentrations inthe composition of the present invention range from about 1% to about 3%alkoxy aminofunctional dialkylpolysiloxane, about 1% to about 3% longchain silicone quaternary blend, about 1% to about 3% silicone fattyamino quaternary blend, about 1% to 3% carboxylic acid, about 5% toabout 17% surfactant, and about 5% to about 17% cosurfactant. Thoseskilled in the art will appreciate other suitable componentconcentration ranges for obtaining comparable physical properties of themanufactured films.

The composition of the present invention comprises a water mix of analkoxy aminofunctional dialkylpolysiloxane chosen from high to lowmolecular weight (or mixes) in a range from approximately 0.002% toapproximately 20%. The alkoxy aminofunctional dialkylpolysiloxaneincludes, but is not limited to:

Where R¹ is an alkyl group, such as, but not limited to, methyl; R² is amonovalent hydrocarbon group having from 1 to 20 carbon atoms or ahalogen-substituted group thereof, and at least 50% of the R² groups aremethyl groups; and Z is an amino-substituted monovalent hydrocarbongroup represented by the formula:R²—(NH—R³)_(a)—NH—R⁴Where R³ is a divalent hydrocarbon group having from 1 to 5 carbonatoms; R⁴ is a hydrogen atom, a monovalent hydrocarbon group having from1 to 20 carbon atoms or a halogen-substituted group thereof; a is anumber of 0, 1, 2 or 3; and x and y are each a positive integer, x+ybeing sufficiently large to give a viscosity from 5 to 100,000centistokes at 25° C.

Protonation of the aminofunctional groups ensures that the alkoxyaminofunctional dialkylpolysiloxane strongly adheres to the surfacewhere the composition is deposited onto, such as vehicle finishes,glass, plastics, chrome, and other metal surfaces. The alkoxy groups ofthe alkoxy aminofunctional dialkylpolysiloxane react with water andgenerate terminal silanol groups (Si—OH) that when deposited onto a hardsurface, will react with other silanol groups from a similar molecule,creating a Si—O—Si bond, causing polymerization, and creating a highlyhygroscopic water-resistant polymeric polish film.

EXAMPLES

The present invention is more particularly described in the followingexamples that are intended as illustrations only, since numerousmodifications and variations within the scope of the present inventionwill be apparent to those skilled in the art. Unless otherwise noted,all parts, percentages, and ratios reported in the following examplesare on a weight basis, and all reagents used in the examples wereobtained, or are available, from the chemical suppliers described below,or may be synthesized by conventional techniques.

The following test method was used to characterize the compositionsproduced in the examples:

Clarity

The samples were visually observed for clarity. Compositions that werenot clear were rejected.

Stability

A sample of the composition was placed in a closed glass container atapproximately 50° C. for a period of at least two weeks. After the twoweek period, the sample was observed for any changes in appearance andfor homogeneity to ensure that the sample did not split into two or morephases.

Another sample of the composition was placed in a closed glass containerand placed on a cycling freezer. The temperature of the cycling freezerdropped to approximately −6.7° C. from room temperature at least fourtimes a day. After the two weeks, the sample was observed for appearanceand homogeneity.

Water Resistance

Metal coupons were made from the metallic gray, clear-coated hood of aGM truck, measuring approximately 4 inches by 2 inches. A solution of 1part of the composition to be tested was diluted to 200 parts water andapplied to the coupons. The coupons were first washed with a 1:10 ratioof Solid Gold to water in order to ensure that debris was removed fromthe coupons. The coupons where subsequently washed with a 1:85 solutionof Velocity 3692 using a soft cellulose sponge saturated with thesolution. Each coupon was rubbed 30 times with the sponge saturated withthe Velocity 3692 solution and then rinsed with tap water, followed bydistilled water, and then placed on a plastic rack having a 26°inclination to air-dry. Each group of four coupons was foamed withapproximately 1.5 grams (each coupon) of the appropriated testingsolution. The foam was spread over the surface of the coupon and rinsedwith tap water, followed by distilled water. The coupons were left onthe plastic rack and allowed to cure for at least 24 hours. The contactangle of a drop of distilled water was then determined for each couponby a FTA. 200 Contac Angle instrument manufactured by First TenAngstroms and controlled by FTA Video Version 1.92 software. Each couponwas tested at four different points. The higher the contact angle, thebetter the water resistance.

A coupon without the film of the composition was washed as describedabove and was used to determine the base line with the contact angleinstrument. The contact angle of a water droplet on the uncoated couponwas determined from the mean value of 16 measurements. The contact anglewas found to be approximately 51°∀4°.

Detergent Resistance

Using the coupons described above, each coated coupon was washed with a1:85 solution of Velocity 3692 using a soft cellulose sponge saturatedwith the solution. Each coupon was rubbed 30 times with the spongesaturated with the Velocity 3692 solution and then rinsed with tapwater, followed by distilled water, and then placed on a plastic rackhaving a 26° inclination to air-dry. The contact angle of a waterdroplet was determined after the wash with the Velocity 3692 solution.This process was repeated 3 times. The higher the contact angle, thebetter the detergent resistance.

Example 1 and Comparative Examples A-E were first tested for clarity andthermal stability, which are illustrated by the data provided inTable 1. In particular, the compositions of Example 1, ComparativeExample A, Comparative Example B, and Comparative Example D were allclear during observation. In addition, the compositions of Example 1,Comparative Example A, and Comparative Example B exhibited thermalstability.

As can be seen in Table 1, the composition of Comparative Example C didnot show good clarity or stability. The stability and clarity of thecomposition were affected by the relatively large amount of alkoxyaminofunctional dialkylpolysiloxane present in the formulation. WhenComparative Example C, which comprised 5.0 wt % of alkoxyaminofunctional dialkylpolysiloxane, was observed for clarity, therewere solids suspended in the solution. Additionally, the composition wasnot homogeneous and lacked thermal stability.

As shown in Table 1, although Comparative Example D showed good clarity,the composition did not show good thermal stability. The composition ofComparative Example D was instable and split when exposed totemperatures below 0° C. The instability of Comparative Example D andComparative Example E was due to the liquid alkylmethyl siloxanecopolyol present in the composition.

After the compositions were tested for clarity and stability, thecompositions showing good clarity and stability (Example 1, ComparativeExample A, and Comparative Example B) were tested for water anddetergent resistance as previously described. As can be seen in Table 2,the water and detergent resistance of the compositions were greatlyaffected by the amount of alkoxy aminofunctional dialkylpolysiloxanepresent in the formulation.

Comparative Example A, which comprised only 0.25 wt % alkoxyaminofunctional dialkylpolysiloxane, had a mean contact angle of 71.91Einitially, which dropped to 63.10E after three washes. ComparativeExample B, which comprised 1.0% alkoxy aminofunctionaldialkylpolysiloxane, had a mean contact angle of 77.91E initially, whichdropped to 73.32E after three washes. In comparison, Example 1, whichcomprised 2.0 wt % alkoxy aminofunctional dialkylpolysiloxane had aninitial mean contact angle of 72.5E, which increased to 79.4E afterthree washes. The increase in contact angle may be due to the washingoff of any residual surfactant trapped by the aminofunctionaldialkylpolysiloxane polymer due to the higher concentration of thealkoxy aminosiloxane used in the formulation. It can be seen that thecontact angle increased after and second wash and then begins todecrease, as expected. The high contact angles, even after severalwashes, indicate the high resistance to water and detergent of thecomposition of the present invention for extended periods of time. Thelower contact angles of Comparative Examples B and C indicate that thefilm formed on the surface to be protected did not adequately protectthe surface after multiple washes.

Although the present invention has been described with reference topreferred embodiments, workers skilled in the art will recognize thatchanges may be made in form and detail without departing from the spiritand scope of the invention.
